Have you tried these? I first found out about them when my sister in law brought them home from the flea market. You can sprinkle lime juice (or lemon, because that's what you have readily on hand), and chili powder on them. I just use lemon juice...no chili powder. They will snap, crackle, and pop a bit when you put them juice on them.
What are they, you ask?
According to Gourmet Sleuth (source of the above photo), they are:
Other names: duritos, durros, pasta para durito
Duros are a Latino snack made of wheat flour and look a bit like a very hard pasta. The traditional shape is a rectangle with grooves but wagon wheel shapes are common too. Typically the duros are deep fried but they can also be microwaved. The prepared duros puff up then can be dipped in salsa or sprinkled with chile lime salt (see Tajin).
Flour, Iodized Salt, Corn Starch, Bicarbonate of Soda, Vegetable Oil and food coloring.
Where can you buy them? I believe Papa Bear got ours at either Lucky or Safeway. You can buy them like pasta and fry them yourself, or you can buy them already fried.
If you try them, let me know what you think!
